I bought these for my son. He is 13 and has been doing BJJ for 4 years now. I bought him the traditional BJJ shorts and he doesn't like the velcro. I was a bit hesitant to buy these because he is in-between sizes and I didn't want to play the return and keep guessing game. I bought him the adult small size with the 5 " inseam. He has a waist of 29 and is stocky about 5'2". The shorts fit him perfectly. The only reason I didn't give 5 stars is because he hasn't been on the mat with them yet, tomorrow will tell us how durable they are. They feel thick and durable. I may be ordering some for myself.
